Donks in Florida are usually so ridiculous that they look like clowns from the circus will be getting out of it. Wheels are like 28” and 30”. They usually have bad glittery paint jobs to.
I love your choice of old cars though. I would like to build a 68-72 C-10. Rag’s

On the 6-71 engines raising more fish, that makes sense. As they are two cycle, the exhaust sound is smoother, like a 12 cylinder engine.

Anybody on here a Dometic dealer? I have called a few and as soon as I say Costa Rica they are gone. I get it with all the scams out there, but if anybody is or knows somebody that can sell me Dometic and answer a few questions, i would be greatly appreciative!!!

That is interesting, makes lots of sense. They also burn diesel like a 12 cylinder...too bad they don't make 12 cylinder power!!

And just to stay off topic while I don't have any good boat pictures to show, this is the truck I'm trying to copy. I think the rims look like 17s, but they might be 16s.

That's not mine, mine is in pieces, but that is what I'm going for. I have a step side like that, and mines a 69 but I'm going to put the 72 grill on it like that one so it'll be a 72 I guess when I'm done?

Mostly fairing lately on the boat. Not too much to show, but we got the top wrap around bench installed, we are going to have to cut out a few hatches. On the left I'm planning on putting all the life jackets and then up front under that one the inflatable life raft. We need two, one will be in the box on the bow, but the other one is in a bag.

And just being honest, I'm not 100 percent happy with how the electronics console looks. I like the idea of having a ton of space to mount everything, but it would have been prettier if I made it less wide and put it in the middle. But then it would be harder to do the cables and stuff. I stuck it on the right side, and then I'm going to make a huge area to put cables in going down to the motors and batteries so that it's easy to replace stuff quickly. If it was a low use private boat I would do it different, but I know there will be days when its dark and raining and I have to change a cable, so I want it to be easy to fix. Hopefully with everything mounted it'll look a little smaller. It's just a lot of blank space now.

If nothing else I took out several hundred pounds. Also with all the benches and everything being one piece, there are no more screws to rot the floor with. Not one screw is being used upstairs now, and everything I put in is foam and very light...

I have a freight forwarder in Miami, so shipping is cheap. I have questions more than anything right now. I have a friend that has a new CU 100 dometic refrigeration unit. Its the cold machine version. And I need two cold plates, one for each box. It looks like the unit can easily cool both boxes when I look at the cubic feet rating, but I was thinking about hooking them up in a serial format (I know one box will get colder first and stay a bit colder and I'm cool with that), can I hook up two cold plates in tandem like that, and which cold plates do I need, and how much would they be. You can PM me or post it here depending on what you think is best for you. Am I doing it right, or should I buy two separate units. I can get the CU-100 for 750 bucks new from the friend.

I guess I need to buy the plates now with the copper tubing, so it's not just questions, the boxes are ready to put in once I have the elements installed.

When you post up pictures, post another of the inside of your boat too. I can't find it and I remember I really liked what you did.

And the aft box and compressors. We molded some thin Perspex with an air gap either side to both maximise cooling effect and protect cold plates from sharp fins etc....



In salon behind port upper settee.

We had Coast Guard inspections last week across the fleet, so that seriously slowed us down, and then we had a pair of motors blow up, and a transmission go out, and a boat hit a log. So it's been a fun week. Hopefully this week I can post some finished projects.

Here's a drone shot of where we are working. Reminds me of the happy ending in Shawshank redemption:

Attachment 1089162



Here's the console upstairs for the electronics. This was from about a week ago, we've already got two layers of fairing done now.

Attachment 1089163



And we replaced alot of the roof of the cabin with foam core and that is all done. The original had some sewed vinyl as a headliner. I can't do that, so we did a grid of 1 by 2's and we are going to do a thing glass sheet on the table for a headliner. We are going to angle the upper corners to put in lights and speakers. That'll make more sense when I shoot a picture. Here's the grid we did on the roof:

Attachment 1089164



And I decided against my ice storage upstairs. We are going to instead just make benchs, and under the benches we are going to have our inflatable rafts and life jackets.

Attachment 1089165


That is a picture from 5 minutes ago. That will all be glassed in before the end of the day though.

Harol is borrowing my crew right now working on a roof, but that should be done this week. Hopefully we can find a groove and get this boat in the water and fishing. I'm aiming for February 1st, and I have already sold a few trips, so I really hope I don't miss. When we start finishing more stuff, I'll post more pictures.

Nice , BTW how much of one of those small
houses in the inlet/bay there , I think I need one with my boat anchored out to look at ...!!!

Ok, so the compressors are smaller than I thought. I keep thinking they are the size of the AC's. Those WAECO boxes look interesting. that seems easy. or the metal plates would work great too. I didn't realize it had to be in the box, I was thinking putting it behind the fiberglass, like glassed onto the back of the inside box. Your way look more efficient. Love how your boat turned out.

It's just hard to find somebody that sells them..

John, I know a lot of the folks we'd talked to say for longevity, the best solution is to put a thin layer of glass over the plates. Maybe Woo's are different though

Still doing alot of sanding. I have some decent pictures of the interior I'll try to post in a bit. But we started on the top. Used my old 2 inch crown formula to cut some plywood jigs and then line them up:

Then we put some foam on top of them and stuck the foam together with Cabosil.

Then here is the tricky part, we propped up the side so it was flat, and glassed one side. Then we flipped it over and let it be curved like the jig and we fiberglassed the other side. When we fiberglassed the second side, we pulled the foam down with thin wire to the jig. After the second side dried, you can pull the wire out leaving very minimal damage. The idea is the foam with one side glassed is very flexible, but once you glass the second side it will not move at all, and will hold it's shape very well.

And then we put some 3m microglobes on the top part to get some sanding in. Probably jumped the gun a little, I want to make the edges 2 inch thick so it look thicker as a whole, and then we need to make a bump where the radar mounts so we can hide the cable up there. We'll get that done soon. I dig through the phone and see if I can find some cabin pictures...

I guess not too much to show. We built some benches on the sides

And then we cut some holes in the top of those benches. We don't have to be too exact because we are putting an awesome big pad on top of the benches, and then another on the wall so usually all this will be covered. You can also see we built a wire chase in the corner of the boat and then we made the top corners of the boat angled and hollow for the lights. I didn't want anything under the middle as that's a pain to get to, but the corners will be nice. We got some nice color changing LED's for the cabin, the cockpit and the bridge. We got all our LED's already from our friend Larry who has helped me a ton on this build at Yacht Supply Depot in Pompano Florida. If only Larry sold chilling plates for my fridges, I'd be set. But everything else he has! The starboard side corner wire chase runs straight from the motor room under the floor right to the controls upstairs. Should make it easy to wire this thing and change stuff when it goes bad!

Then stuck another piece of foam below the holes as door jams.

And then took the part we cut out and made doors I hate hinges, so they just sit there, but again, there will be a big pad.

We still haven't drawn the new windows yet, but that is not how they are going to look when we are done...
